Description

The theftproof lock of dead bolt band barb and comprise the world lock of this theftproof lock

Technical field

The present invention relates to five metals and make the field, be specifically related to a kind of theftproof lock of dead bolt band barb and comprise the world lock of this theftproof lock.

Background technology

The lock construction that sell general market mainly is to utilize dead bolt to contact with the rigidity of latch plate, prevents to destroy lock body and latch plate and is pried open.In case but lock body or latch plate fracture, then door can be opened easily.As long as the invador applies active force or the moment that can bear greater than dead bolt and latch plate, make the fracture of dead bolt or latch plate, the invador can open door in seconds or tens of seconds.

Summary of the invention

The present invention is in order to overcome the deficiency that above prior art exists, and a kind of theftproof lock of dead bolt band barb of rational in infrastructure, good anti-theft effect is provided.

Lock in the world that another object of the present invention is to provide a kind of anti-theft effect better to comprise this theftproof lock.

Purpose of the present invention realizes by following technical scheme: the theftproof lock of this dead bolt band barb, it is characterized in that: comprise buckle and lock body, be provided with dead bolt, barb reseting plate and swing arm in the described lock body, be hinged with barb in the dead bolt, swing arm and lock body are hinged, and an end of swing arm is connected with dead bolt.

Described dead bolt has a cylindrical protrusions, and lock body has slotted hole one, and projection is slided in slotted hole.

Described swing arm is a shape.

Described buckle has twice distortion guiding groove and a square hole, the maximum longitudinal size when square hole perforate longitudinal size stretches out less than dead bolt and barb.

The manufactured materials of described buckle is high-tensile stainless steel, and perhaps other has the metal of tensile characteristics.

The world lock that comprises this theftproof lock, it is characterized in that: comprise two theftproof locks and a main lock, described main lock comprises main buckle and main lock body, main lock body is provided with the panel handle, a theftproof lock is positioned at the main side of locking, and be connected with main lock by last connecting rod, another theftproof lock is positioned at main lock below, and is connected with main lock by lower link.

A described end of going up connecting rod is connected with the swing arm of a theftproof lock, and the other end is connected with the slide block of main lock body, and an end of lower link is connected with the swing arm of another theftproof lock, and the other end is connected with the slide block of main lock body.

The present invention has following advantage with respect to prior art: the theftproof lock of this dead bolt band barb, and when being in locked state, dead bolt is stirred in swing arm, and dead bolt stretches into the square hole of buckle, and buckle is hooked in the barb rotation in the dead bolt; When being in opening, dead bolt is stirred in swing arm, and the barb in the dead bolt is under the barrier effect power of barb reseting plate, in the rotation withdrawal dead bolt, in the dead bolt withdrawal lock body.The barb of dead bolt stretches out when theftproof lock is sealed, in the indentation dead bolt tunnel, does not influence the switch door when theftproof lock is opened.

Barb stretches out with buckle and detains on all directions extremely when locking states, dead bolt can't be pulled out the square hole of buckle.When external force is better than when prying open or opening, guiding distortion groove by barb on the dead bolt and buckle, the barb button of dead bolt is stubbornly refused to cause and is skidded off buckle, and utilize the distortion of buckle to draw back crack between a door and its frame, because of the crack between a door and its frame gap becomes the ineffective power fulcrum of instrument that ambassador forces open the door, reduce and prize moment, can't apply opplied moment to door lock again, under this sight,, enlarge crack between a door and its frame though door is pried open, but dead bolt barb and buckle still are bound up and can not break away from, dead bolt can not rupture, and buckle is to tractive force direction distortion and don't can rupture, invador's destruction theftproof lock that can't remain valid.The good anti-theft effect of the theftproof lock of this dead bolt band barb.

For the world lock that comprises two theftproof locks and a main lock, when little toggle on the panel or the sealed world of key lock, connecting rod and lower link in the slide block push-and-pull of main lock body, the swing arm of upper and lower strut control theftproof lock, make theftproof lock sealed, main simultaneously lock body and main buckle are sealed; When little toggle on the panel or key operated world lock, connecting rod and lower link in the slide block push-and-pull of main lock body, the swing arm of upper and lower strut control theftproof lock is opened theftproof lock, and main simultaneously lock body and main buckle are opened.Originally comprise the world lock of this theftproof lock, owing to used two theftproof locks, anti-theft effect further improves.
